This may be your most inaccurate review in the entire site. Not only is it too violent for a 6 year old, but it also is a very funny show with a good sense of surrealistic humor. First, the violence: a three headed kracken is killed on-screen and the inside of its heads is shown, another kracken is killed as well (I can't remember how though), Gordon is seen in a detailed transformation to a monster, zombies are killed with lazers, and so on. In a sense, this is kind of the Courage the Cowardly Dog of the 2000's. The only difference is that it's not QUITE as explicitly gory. But any child under 7 would certainly be unsettled by this show. However, it has a good sense of humor, as it is partially dialogue-driven and partially surrealistic humor-driven. I don't think I can explain how the surrealism of the show is funny, because that sense of humor is an acquired taste. But I can definetly tell you that I think this is one of Nick's funnier 2000's Nicktoons, and that's coming from someone who actually grew up in that era and isn't afraid to admit it.
